Abstract: One embodiment relates to a method for automated correction of duplex mismatches. A duplex mismatch is detected at a port of a network device, and characteristics of the duplex mismatch are determined. The configuration of the mismatched port is automatically modified based upon said characteristics. Another embodiment relates to an apparatus for automated correction of duplex mismatches. The apparatus includes a duplex mismatch detector and an automated duplex mismatch fixer. The duplex mismatch detector is configured to detect a duplex mismatch at a port of a network device and to determine characteristics of the duplex mismatch. The automated duplex mismatch fixer is configured to modify a configuration of the mismatched port based upon said characteristics. Other embodiments and features are also disclosed.

Abstract: In an embodiment, a method for finding duplex mismatches in a copper based network, includes: detecting late collisions and cyclic redundancy check (CRC) errors; if a port is in auto-negotiation and up in half-duplex and over threshold late collisions have been detected, then informing the user of a duplex mismatch and suggesting to the user to set the port to full duplex; and if the port is in forced full-duplex mode and over threshold CRC errors have been detected, then informing the user of a duplex mismatch and suggesting to the user to set the port to auto-negotiations mode.
